Given a mother wavelet, an orthogonal family of wavelets can be obtained by properly choosing a= am 0 and b= nb 0, where mand nare integers, a 0 >1 is a dilation parameter, and b 0 >0 is a translation parameter. To ensure that wavelets ψ a,b, for fixed a, “cover” f(x) in a similar manner as mincreases, we choose b 0 = βam 0. For rapid ...

The envelope of the secondary wavelets emanating from F 1 F 2 produces the forward moving wavefront G 1 G 2. The backwave D 1 D 2 does not exist. Thus, if we wish to determine the shape of the wavefront at t = τ, we draw spheres of radius vτ from each point on the spherical wavefront where v represents the speed of the waves in the medium.
